ISO 34-1:2022 硫化橡胶或热塑性橡胶 撕裂强度的测定 第1部分：裤形、直角形和新月形试样

标准编号：ISO 34-1:2022

中文名称：硫化橡胶或热塑性橡胶 撕裂强度的测定 第1部分：裤形、直角形和新月形试样

英文名称：Rubber, vulcanized or thermoplastic — Determination of tear strength — Part 1: Trouser, angle and crescent test pieces

发布日期：2022-06

标准范围

本文件规定了三种测定硫化橡胶或热塑性橡胶撕裂强度的试验方法，即:—？方法A，使用裤子试件；—？方法B，使用角度试件，有或没有规定深度的刻痕；—？方法C，使用带缺口的新月形试件。获得的撕裂强度值取决于试件的形状、拉伸速度和试验温度。它也容易受到橡胶颗粒效应的影响。注意ISO？中规定了测定小橡胶试件（代尔夫特试件）撕裂强度的单独方法34-2.

This document specifies three test methods for the determination of the tear strength of vulcanized or thermoplastic rubber, namely the following:—    method A, using a trouser test piece;—    method B, using an angle test piece, with or without a nick of specified depth;—    method C, using a crescent test piece with a nick.The value of tear strength obtained depends on the shape of the test piece, speed of stretching, and temperature of test. It can also be susceptible to grain effects in rubber.NOTE       A separate method for the determination of the tear strength of small test pieces of rubber (Delft test pieces) is specified in ISO 34-2.
